Mesoporous Metal Oxide/Pyrophosphate Hybrid Originated from Reutilization of Water Treatment Resin as A Novel Fire Hazard Suppressant
Antimony trioxide (Sb2O3) is a traditional flame retardant in flexible poly(vinyl chloride) (fPVC).However, the underlying hazard and decreasing reserve in the earth crust obligate the development of its substitutes.In this work, mesoporous SnO2/Ca2P2O7 hybrid crystals (TCP) with high specific surface area and pore volume was firstly synthesized as flame retardant via a facile way by reutilizing the available chelating resin after treated with groundwater as the precursor.The results from limiting oxygen index test (LOI), UL-94 vertical burning test and cone calorimeter test showed that the addition of 5 phr as-synthesized product reduced the fire and smoke hazards of fPVC, attributed to the combined impact of SnO2 and Ca2P2O7.This novel flame retardant has the great potential to replace antimony trioxide and provides the promising route to develop sustainably flame-retardant fPVC composite with free of Sb2O3.
